s claims. (c1. 2x1- 19) My present invention, in its broad aspect, hasto do with improvements in binders or holders for memorandum books,pads, checks, perforated blank books and pads and the like, and thecover therefor may be fabricated of a single sheet of leather, or othermaterial, or the cover may have pockets, or a lining, or a stitchedstrip to hold my device. My binder operates without a rod, or the like,passing through and between parts of the object bound, such as amemorandum book or pad, and eliminates the necessity oi stitching theleaves of the pad together, or if the pad be stitched, my binder willoperate upon it just as well as without stitches, and no rivets, screws,or the like, are used with my device, nor will it scratch a desk or thelike.

In addition to the above, my binder is simple, sturdy and practical andis easily and quickly assembled without screws or rivets, and comprisesbut four simple and cooperating parts, namely, a hollow tubular bar toform the back, a flat strip with tongues locking to the back, andcarrying a rod, and a clamping or gripping retainer to hold the pad ornotebook, or the like, and which is mounted on the rod, and which issubstantially U-shaped in cross section. With these simple and improvedparts, my device is easily assembled and can be manufactured and sold ata relatively small price.

Other and equally important objects and advantages of my invention willbe apparentfrom the following description and drawings, and changes maybe made in size, shape, form, materials, and construction andarrangement of parts, and are within the purview of my broad inventiveconcept and the scope of the appended claims.

In the drawings, wherein I have illustrated a preferred embodiment of myinvention- Figure 1 is a View of my binder and cover opened up andholding a perforated pad;

Figure 2 is a section on the line 2-2 of Figure l;

Figure 3 is a section on the line 3-3 of Figure 2;

Figure 4 is a detail perspective of an end of the flat strip with theattaching tongue and the raised support to receive an end of the rod;

Figure 5 is a vertical section showing the manner of assembling mydevice;

Figure 6 is a top plan view of the hollow tubular back;

Figure '1 is an endview of the hollow tubular back;

Figure 8 is an enlarged section showing the tongues of the flat striplocked to the hollow tubular bar by the upwardly bent end lips;

.parts `throughout the several views:

s z I, Figure 9-is a section on the line 9-9 of Figure 4; Figure 10 is amodified form showing binding or attaching prongs struck outof theLl-shaped clamping or gripping retainer, and

Figure .l1v isa section on the line II--II of Figure 10.

In the drawings, lwherein like characters of reference are used todesignate like or similar The numeral I designates the cover to which isstitched as at 2, a lining 3. VThe cover has a pocket 4 and is foldedmedially between its side edges to form a front and back cover. At themedial point, or the point of fold, the lining 3 is slit top and bottomas at 5 to receive therethrough between the cover and the lining my flattubular back 6. My nat tubular back has extended lips 'I at the endswhich are bent upwardly as shown in Figure 8. A flat strip 8 is placedover and parallel with the tubular back 6 and between the two is thematerial of the lining 3 as shown in Figure 8. The flat strip hasreinforcing and stiffening corrugations 9, and upwardly, and over anddownwardly bent end parts I0 forming supports for a rod II, the ends ofwhich pass through holes Ilia in the supports I Il. The downwardly bentportions I2 of parts I 0 are extended to form tongues I3 which are bentinwardly into the tubular back-as shown in Figure 5to hold the strip inplace on the back, with the lips 1 forming stops. A pad clamping andretaining device I4 is formed substantially U-shaped in cross section togo about the rod II and if desired, the retainer may be soldered orspot-welded to the rod or simply clipped around the rod as shown inFigure 2 with the back and front, respectively I5 and I6 of the retainerinstruck on opposed lines to form retaining beads I1 for the wirestitches if the pad is thus fastened together. The notebook or pad (I8)is frictionally retained between the back and front, I5 and I6respectively-as shown in Figure 2. If desired, instruck tabs orretaining bars ISS-see the modied form of Figures l() and ll-may beprovided to lock the clamping and retaining member on the rod.

From the foregoing, it is believed that the operation and advantages ofmy inventionwill be apparent, but it is again pointed out that,`interpretation of its scope should only be conclusive when made in theVlight of the subjoined claims.

I claim: y Y 1. The invention as defined in claim 6 wherein the coverhas a member attached thereto between which and .the cover .the v`backbar eX tends with .the iat iretaining :strip abovethe member. k2. Theinvention as defined in claim 6 wherein the bent, end portions of thestrip are formed with openings, the rod having its ends detachablyandmovably engaged in the openings'.A

parts 'engaging vover the rod to hold the :clamping and retaining memberthereon.

5. 'The invention as'deinedfin claim A-16 where-V -in 'the strip 4isformed'with reinforcing corrugations, and wherein Ithe :bent Yendl parts'forming Lsupports are substantially fV-shaped'in ,':cross l5 3. Theinvention as defined in claim v6'wl1erein f section with the outer legextended down at' an angle and formed with a tongue,

6. A binder and holder for pads and the like,

comprising a cover part, a hollow back bar engaged with the cover, a,flat retaining strip attached at its ends to the back bar to hold thesame in place on the cover, and provided with Y' upwardly and downwardlybent end portions forming supports,V tongues on said bent end portions,:bent to `engage in the ends :of .ithe Vback "bar, lips a'tthe ends ofthe back b'ar bent to form retainers for the tongues a, rod carried be-V'tween the supports, said rod being pivotally and detachably engagedwith the supports and a notebook retainingdevice carried on the rod.
